' 2 Claims. (01. 285172) This invention relates to vacuum cleaner con- 2|. I preferably'provide two clamps l9 and as a duits. I third securing member I may provide a clip 22 The general object of my invention is to promounted on the housing and pr j n v h vide a vacuum cleaner conduit including novelly top of closure 18. The closure I8 is notched as connected detachable sections. at 23 to receive the clip and to aid in centering. 5 A- more specific object of the invention is to From the closure l8 an offset conduit 24 exprovide a novel detachable connection for a vactends- This Conduit is p v W a enlarged uum cleaner c d it, cylindrical skirt portion 25 in which a collar Another object of theinvention is to provide 26 on a cap 21 is arranged The C u po t n a novel means for connecting a vacuum cleaner 24 is engaged by a p 23 similar to p 22 a 10 conduit to a cleaner body. which projects through a notch 29 on the cap 21.

The hose 34 is cemented in a This application is a continuation-in-part of collar 42 which is flared as at 43 at the end my co-pending application, Serial No. 58,491, o a w flexibility n e hosefiled January 10, 1936, which matured into Pate Collar 42 s p d d ntermediate its 40 ent No. 2,112,978. length with a flange 44 which engages the flange 40 Referring to the drawings by reference charac- 39 as shown in A split p n member 45 is ters I have shown my invention as embodied in disposed in e ent W th the flanges 4| and 44 a vacuum cleaner which is indicated generally at to thereby allow a swivelling action between the I0. As shown the cleaner includes a housing I I handle a the e Without udinal move- 45 in which a suitable motor and fan may be ment between these p 45 mounted. The section 35 is connected to the section 36 The upper portion I2 of the housing is proand the section 36 is connected to the section vided with an annular ring I4 which is secured 31, each by a joint 50. Each joint includes an in place by means such as bolts l5. expanded portion 5| which terminates in a bulb- 50 The ring is rabbeted at IE to receive a flanged ous bead 52 and includes an outwardly pressed 50 collar I! on which a fabric dirt bag Bis mounted. boss 53 on which a locking lever 54 is pivoted The ring I4 is provided with a closure I8 by means of a rivet 55. The locking lever inwhich is held in place by securing clamps [9 which cludes a finger engaging portion 56 on one side are pivoted by screws 20 to the housing. The of the pivot and a hook portion 51 on the other 55 clamps [9 each include finger engaging portions side of the pivot. The hook portion has a slot 55 which is indicated at 58 and which has an undercut face. The bulbous portion 5| is notched as atwith the notch so disposed that it is in alignment with the slot when the lever is in one position.

The portion of the section 31 adjacent to the section 36 is provided with a protruding head 62 against which a gasket 63, which may be an inexpensive rubber band, is fitted and beyond the bead the section 35 is cylindrical as at 64. Beyond the cylindrical portion 64 the length is slightly tapered as at 65 to allow ready assemblage. The tapered end 65 is arranged the direction of fiow as indicated by the arrow in Fig. 10 so that there is no likelihood of dirt lodging in the joint.

In assembling the parts the locking lever 54 is moved to open position and the lengths are moved to the position shown in Figs. 9 and 10. The locking lever is then swung on its pivot and engages a post 66 on the cylindrical portion 63. The post is fitted within the notch Bl] on the bulbous portion 6| and when the lock lever turns this post is engaged between the walls of the slot thus bringing the parts together and compressing the gasket 63.

The lower portion of the forward end of the finger engaging portion 36, as indicated at 61, presses against the adjacent portion of the iength 34 and the friction thus developed between these engaging portions serves to hold the parts assembled. Attached to the outer end of the length 31 I show a swivel 19 which may be connected to a suitable nozzle 'H. The nozzle, however, forms no part of the present invention and is merely typical of a number of implements which may be secured to the handle portion.

From the foregoing description it will be apparent that I have invented a novel vacuum cleaner conduit which can be readily manufac= tured and which is highly efiicient in use.

Having thus described my invention, I claim:

1. In a vacuum cleaner, a conduit, a handle member comprising a plurality of lengths of hollow tubes, said tubes ineluding inner and outer telescoping end portions, said inner end having a bead therein, said outer end having a peripheral outwardly extending bead adjacent to the bead on the inner portion, said outer end having a boss thereon, a locking lever pivoted on said boss, said inner tube having a post thereon, said outer tube having a straight slot in said boss receiving said post, said lever including a hand engaging portion at one end and including a transversally extending notch spaced on the other end of said lever receiving said post.

2. In a vacuum cleaner, a conduit, a handle member comprising a plurality of lengths of hollow tubes, said tubes including inner and outer telescoping end portions, the inner end portions including a cylindrical portion and an inwardly tapered extremity, the outer end portions comprising a cylindrical portion, an outwardly tapered portion and a cylindrical extremity on the outwardly tapered portion, said cylindrical portion on the outer end portion being disposed contiguous with the cylindrical portion on the inner portion, said inner end portion having a bead therein, said outer end portion having a peripheral outwardly extending bead adjacent to the bead on the inner portion, said outer end portion having a boss thereon, a locking lever pivoted on said boss, said inner portion having a post thereon, said outer portion bead having a straightslot receiving said post, said lever including a hand engaging portion at one end and including a transversally extending notch spaced on the other end of said lever, said netch receiving said post.
